ミキシング制御回路。In a tape recorder equipped with a recording/playback magnetic head that operates as a recording magnetic head and a playback magnetic head by switching a recording/playback switch, the playback signal from the magnetic head is amplified during playback operation, and the recording signal is amplified during recording operation. A recording/playback amplification circuit that amplifies the sound, a built-in microphone attached to the tape recorder body,
A microphone jack into which an external microphone plug is inserted, a microphone amplification circuit that amplifies the signal from the microphone jack, a selection switch that switches between using a tape recorder and using an external signal such as a radio receiving device, and a speaker as a load. and a main amplification circuit connected to the tape recorder, and during playback operation when the selection switch is on the tape recorder use side, the playback signal from the recording/playback amplification circuit and/or the signal from the microphone amplification circuit is amplified by the main amplification circuit. At the same time, during a recording operation, a signal from the built-in microphone and/or the microphone amplifier circuit is input to the recording/playback amplifier circuit, so that the output signal of the recording/playback amplifier circuit is input to the recording/playback amplifier circuit. The signal is applied to the head and the main amplifier circuit, and the signal from the microphone amplifier circuit is applied to the main amplifier circuit during operation when the selection switch is on the external signal use side, and the signal is applied to the main amplifier circuit during recording operation. The external signal and/or the signal from the microphone amplifier circuit is amplified by the recording/playback amplifier circuit and then applied to the recording/playback magnetic head, and the external signal and/or the signal from the microphone amplifier circuit is amplified by the recording/playback amplifier circuit. A mixing control circuit for a tape recorder, characterized in that the voltage is applied to the main amplifier circuit without passing through the recording/playback amplifier circuit.
